Hanging out at the LHC: CMS, ATLAS and CERN control rooms - Part 2

CMS, along with the ATLAS experiment and CERN, organised a Google+ Hangout inviting you into the nerve centres controlling the Large Hadron Collider as well as its two general-purpose experiments, CMS and ATLAS: cern.ch/go/Q97l.
This is the full video of Part 2 of the two-part Hangout, held at the start of the LHC's world-record-breaking run at an energy of 8 TeV (or teraelectronvolt). Part 1 can be found here: cern.ch/go/9KQM
